Fix outdated lfu-decay-time doc in redis.conf (#11108)
The divided by two and less <= 10 logics were changed in 06ca9d683920da19ad53532f8cd55b54584027bc.
Now we just decrement the counter by num_periods.
The lfu-decay-time special value of 0 's meaning was actually changed in 06ca9d683920da19ad53532f8cd55b54584027bc.
Now we won't do anything on counter if lfu-decay-time is 0.
